Combining the gas trapping ability of military carbon cloth and HEPA's particle filtration Austin engineers have created HEGA filtration - High Efficiency Gas Adsorption. When the air moves through this carbon cloth filter, it eliminates unwanted odors caused by animals, cooking, smoke, and chemicals. The unique weave of the cloth filter reduces dust while increasing the surface area, helping the filter perform more efficiently, weigh less, and last longer.
The HEPA (High Efficiency Particle Arresting) filter provides optimum filtration of pollen, dust, dander, and other respiratory irritants. HEPA removes a minimum of 99.97% of all particles greater than 0.3 microns in size (A human hair is about 300 times too large to penetrate a HEPA). Researchers at the Austin laboratories developed a method for combining the gas trapping capabilities of the carbon cloth, with the proven particle filtration of the HEPA filter. The result is the highly efficient HEGA filter. The HEGA lasts up to 30 times longer than conventional carbon/zeolite filters and weighs 13 pounds less.
